McMillan 6 X 47 Barrel

[dfletcher]

I just bought a slightly used .920 diameter 20" stainless steel "McMillan Gold Stock" barrel in 6X47/222RM for a Remington 700. I have a Remington 700 chambered in 300 AAC as a "donor" and already reload for the 6X47 cartridge. Mag follower, case head diameter are the same, am I correct that a barrel change & headspacing should complete the change?

Yes.

Id be interested in the take off barrel for another project of mine if selling, what is the twist on the 300aac barrel? 7", 8"?

The 6X47 is a bit longer than a standard 223/300AAC cartridge. You may need to find a 222 REM MAG follower and magazine block. Check the Remington parts list for the part numbers.

Rate of twist is 1 in 7" and the barrel is a varmint profile, 16" with a 5/8X24 threaded muzzle. Once I check with the fellow doing the work, ensuring the new barrel will work, etc - I'll let you know first.
